What are the common actuators in process flow?

Actuator, also known as actuator, is a commonly used electromechanical integration device (device) in the field of automatic control, and it is the actuator in the three major components of automatic instruments (detection device, adjustment device and execution device). Mainly to automatically operate some equipment and devices, control their switches and adjustments, instead of manual operation. According to the type of power, it can be divided into pneumatic, hydraulic, electric and electro-hydraulic types. According to the form of motion, it can be divided into straight stroke, angular stroke, rotary (multi-rotary) and so on The electric actuators developed and produced by Shanghai Cohen Automation Equipment Co., Ltd. mainly include G series electric actuators, Ken series electric actuators and JZ series multi-rotary gear boxes. Because using electricity as power has incomparable advantages over other media, electricity has developed rapidly and been widely used in recent years. According to different standards, electric type can be divided into: combined structure and electromechanical integration structure; Electrical control, electronic control and intelligent control (with HART and FF protocols); Digital type and analog type; Manual contact debugging and infrared remote control debugging.
